Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The first embodiment is as follows:
referring to fig. 1-2, a grinding wheel comprises a grinding wheel body 1 and a connecting structure, wherein the connecting structure is fixedly connected with the grinding wheel body 1;
the connecting structure comprises a fixed head and a connecting head 2 which are fixedly connected.
Referring to fig. 1-2, the fixing head is an embedded fixing head 3, and a small grinding wheel is used for grinding marble, so that the embedded fixing head 3 is arranged, and the centrifugal force can be overcome by only connecting the embedded fixing head 3 with the grinding wheel body 1 at the middle position;
the embedded fixing head 3 comprises a connecting plate 31 and a first gripper 32 which is positioned around the connecting plate 31 and formed by bending, namely the connecting structure is connected with the grinding wheel body 1 through the gripper 32;
